I like to experiment with applying cyanotype emulsions to glass plates. I think to be able to do this by applying a gelatin layer to the glass first. My problem is: I know very little about applying emulsions or gelatin to glass plates! Who can point me to some literature, or who knows what to watch for? Here is what I like to learn: 1. Does the glass need special cleaning? 2. What type of glass is best? 3. What type of gelatin will do? 4. Do I need a hardener for the gelatin, and if ?yes¹, which hardener? 5. How do I prevent bacteria grows, or is this not to worry about? Regards Ralph W.
